Patent number: 10054812Abstract: A first substrate includes a plurality of pixel electrodes, a plurality of common electrodes on which slits are disposed at predetermined intervals in a first direction and which extend in a second direction, and a plurality of auxiliary wirings that are in contact with and overlap the common electrodes. A second substrate includes a plurality of spacers, a plurality of wall-like sub-spacers, and a color filter layer in which adjacent pixels have different colors from each other. The wall-like sub-spacers are disposed at positions that overlap the slits.Type: GrantFiled: June 21, 2017Date of Patent: August 21, 2018Assignee: Japan Display Inc.Inventors: Kanae Kobayashi, Shigeo Nakagawa

Patent number: 7667798Abstract: The present invention provides a liquid crystal display device which can enhance quality and reliability of image display by preventing the generation of bubbles in the inside of a liquid crystal display panel and, at the same time, by suppressing leaking of light from an end of a black matrix film. In the liquid crystal display panel which sandwiches a liquid crystal layer between two glass substrates, the liquid crystal layer is surrounded by a sealing material having a predetermined width. On one glass substrate, a black matrix film and an overcoat film are arranged from one-glass-substrate side such that the black matrix film and the overcoat film overlap the sealing material. The black matrix film is, in the widthwise direction of the sealing material, formed into a planar flat black matrix film until a middle position of the sealing material from a side on which the liquid crystal layer is arranged, and is formed into a slit-shaped slit black matrix film from the middle position.Type: GrantFiled: January 22, 2008Date of Patent: February 23, 2010Assignee: Hitachi Displays, Ltd.Inventor: Shigeo Nakagawa

Patent number: 5982388Abstract: An image presentation device comprises an object information storage part which receives a scenario consisting of object information describing the attributes of an appearing object and an attribute changing procedure describing a procedure for changing the attributes of the appearing object and storing the object information contained in the scenario. An attribute changing procedure storage part receives the scenario and stores the attribute changing procedure contained in the scenario. An attribute changing part changes the attributes of the object information according to the attribute changing procedure. An object information calculating part calculates a position of the appearing object in a virtual space according to the object information whose attributes have been changed by the attribute changing part, an image generating part generates an image according to the calculated results by the object information calculating part.Type: GrantFiled: September 1, 1995Date of Patent: November 9, 1999Assignee: NEC CorporationInventor: Shigeo Nakagawa

Patent number: 5821946Abstract: An interactive picture presenting apparatus includes a user input section, an operation data generating section, an operation unit generating section, a scenario editing section, and an interactive picture generating section. The user input section receives a user input. The operation data generating section generates operation data of the objects on the basis of layouts of the objects for each frame. The operation unit generating section generates, on the basis of the user input from the user input section, an operation unit constituted by the operation data from the operation data generating section and a start condition of the operation data. The scenario editing section generates, on the basis of the user input from the user input section, a scenario using the operation unit from the operation unit generating section and an execution order of operation units.Type: GrantFiled: January 13, 1997Date of Patent: October 13, 1998Assignee: NEC CorporationInventor: Shigeo Nakagawa

Patent number: 5689437Abstract: In a video display method of laying out a plurality of objects in a space, and creating images of the objects in units of frames, thereby displaying a series of videos, geometric attributes of first and second objects, movements of the first and second objects, including changes in the first and second objects, first and second start positions of the movements, and first and second start times of the movements are defined as first and second scenarios. First and second occupied areas occupied when the first and second objects move on the basis of the first and second scenarios are calculated by approximating the ORs of a sequence of areas occupied by the first and second objects when the first and second objects take the movements at the first and second positions and the first and second times on the basis of the first and second scenarios. A common area where the first and second occupied areas cross each other is calculated. The first and second occupied areas and the common area are displayed as video.Type: GrantFiled: May 31, 1996Date of Patent: November 18, 1997Assignee: NEC CorporationInventor: Shigeo Nakagawa
